          3.1 Revolving Loans.

               (a) Revolving Commitment. During the Revolving Commitment Period,
          subject to the terms and conditions hereof, each Lender severally
          agrees to make revolving credit loans ("Revolving Loans") to the
          Borrower from time to time for the purposes hereinafter set forth;
          provided, however, that (i) with regard to each Lender individually,
          the sum of such Lender's share of outstanding Revolving Loans plus
          such Lender's LOC Commitment Percentage of LOC Obligations shall not
          exceed such Lender's Revolving Committed Amount, and (ii) with regard
          to the Lenders collectively, the sum of the aggregate amount of
          outstanding Revolving Loans plus the aggregate amount of LOC
          Obligations shall not exceed FORTY MILLION DOLLARS ($40,000,000) (as
          such aggregate maximum amount may be reduced from time to time as
          provided herein). Revolving Loans may consist of Prime Rate Loans or
          Eurodollar Loans, or a combination thereof, as the Borrower may
          request, and may be repaid and reborrowed in accordance with the
          provisions hereof. Eurodollar Loans shall be made by


                                      -22-

          each Lender at its Eurodollar Lending Office and Prime Rate Loans at
          its Domestic Lending Office.

               (b) Revolving Loan Borrowings.

                    (i) Notice of Borrowing. The Borrower shall request a
               Revolving Loan borrowing by written notice (or telephone notice
               promptly confirmed in writing which confirmation may be by fax)
               to the Agent not later than 10:30 A.M. (Milwaukee, Wisconsin
               time) on the Business Day of the requested borrowing in the case
               of Prime Rate Loans, and on the third Business Day prior to the
               date of the requested borrowing in the case of Eurodollar Loans.
               Each such request for borrowing shall be irrevocable and shall
               specify (A) that a Revolving Loan is requested, (B) the date of
               the requested borrowing (which shall be a Business Day), (C) the
               aggregate principal amount to be borrowed, and (D) whether the
               borrowing shall be comprised of Prime Rate Loans, Eurodollar
               Loans or a combination thereof, and if Eurodollar Loans are
               requested, the Interest Period(s) therefor. A form of Notice of
               Borrowing a ("Notice of Borrowing") is attached as Exhibit
               2.1(b)(i). If the Borrower shall fail to specify in any such
               Notice of Borrowing (I) an applicable Interest Period in the case
               of a Eurodollar Loan, then such notice shall be deemed to be a
               request for an Interest Period of one month, or (II) the type of
               Revolving Loan requested, then such notice shall be deemed to be
               a request for a Prime Rate Loan hereunder. The Agent shall give
               notice to each Lender (promptly upon receipt of each Notice of
               Borrowing, and in any event not later than 12:00 noon, Milwaukee,
               Wisconsin time, with respect to any Notice of Borrowing delivered
               to the Agent pursuant to this section) of the contents thereof
               and each such Lender's share thereof.

                    (ii) Minimum Amounts. Each Revolving Loan borrowing shall
               be: (A) if a Prime Rate Loan, in a minimum aggregate amount of
               $500,000 and integral multiples of $100,000 in excess thereof;
               and (B) if a Eurodollar Loan, in a minimum aggregate amount of
               $1,000,000 and integral multiples of $500,000 in excess thereof
               (or, in either case, the remaining amount of the Revolving
               Commitment, if less).

                    (iii) Advances. Each Lender will make its Revolving
               Commitment Percentage of each Revolving Loan borrowing available
               to the Agent for the account of the Borrower at the office of the
               Agent specified in Schedule 12.2, or at such other office as the
               Agent may designate in writing, by 1:30 P.M. (Milwaukee,
               Wisconsin time) on the date specified in the applicable Notice of
               Borrowing in Dollars and in funds immediately available to the
               Agent. Such borrowing will then be made available to the Borrower
               by the Agent by crediting the account of the Borrower on the
               books of such office with the aggregate of the amounts made
               available to the Agent by the Lenders and in like funds as
               received by the Agent by the close of Agent's business on such
               date.

               (c) Repayment. The principal amount of all Revolving Loans shall
          be due and payable in full on the Revolving Termination Date.

                  (d)      Interest. Subject to the provisions of Section 4.1,
         Revolving Loans shall bear interest as follows:

                           (i)      Prime Rate Loans. During such periods as
                  Revolving Loans shall be comprised of Prime Rate Loans, each
                  such Prime Rate Loan shall bear interest at a per annum rate
                  equal to the sum of the Prime Rate plus the Applicable
                  Percentage;

                           (ii)     Eurodollar Loans. During such periods as
                  Revolving Loans shall be comprised of Eurodollar Loans, each
                  such Eurodollar Loan shall bear interest at a per annum rate
                  equal to the sum of the applicable Eurodollar Rate plus the
                  Applicable Percentage as of the commencement of the Interest
                  Period applicable thereto; and

Interest on Revolving Loans shall be payable in arrears on each Interest Payment
Date.

                  (e)      Revolving Notes. The Revolving Loans shall be
         evidenced by a duly executed promissory note of the Borrower to each
         Lender in the original principal amount of each such Lender's Revolving
         Committed Amount in substantially the form of Exhibit 3.1(e).

         3.2      Letter of Credit Subfacility.

                  (a)      Issuance. Subject to the terms and conditions hereof
         and of the LOC Documents, if any, and provided that no Default or Event
         of Default shall have occurred and be continuing, and further subject
         to any other terms and conditions which the Issuing Lender may
         reasonably require, during the Revolving Commitment Period the Issuing
         Lender shall issue, and the Lenders shall participate in, Letters of
         Credit for the account of a Credit Party from time to time upon request
         in a form acceptable to the Issuing Lender; provided, however, that (i)
         the aggregate amount of LOC Obligations shall not at any time exceed
         THREE MILLION FIVE HUNDRED THOUSAND DOLLARS ($3,500,000) (the "LOC
         Committed Amount") and (ii) the sum of the aggregate amount of
         Revolving Loans plus the aggregate amount of LOC Obligations shall not
         at any time exceed the aggregate Revolving Committed Amount. No Letter
         of Credit as originally issued or as extended shall have an expiry date
         extending beyond the Revolving Termination Date, except that prior to
         the Revolving Termination Date a Letter of Credit may be issued or
         extended with an expiry date extending beyond the Revolving Termination
         Date if, and to the extent that the Borrower shall provide cash
         collateral to the Issuing Lender on the date of issuance or extension
         in an amount equal to the maximum amount available to be drawn under
         such Letter of Credit. Each Letter of Credit shall comply with the
         related LOC Documents. The issuance and expiry date of each Letter of
         Credit shall be a Business Day. In the case of a conflict in the terms
         of the LOC Documents and this Credit Agreement, the terms of this
         Credit Agreement shall control.

                  (b)      Notice and Reports. The request for the issuance of a
         Letter of Credit shall be submitted to the Issuing Lender and the Agent
         on such prior notice as the Issuing


                                      -24-

<PAGE>   30


         Lender and Borrower shall agree. The Issuing Lender will, at least
         quarterly and more frequently upon request, provide to the Agent (who
         shall promptly disseminate to the Lenders and the Borrower) a detailed
         report specifying the Letters of Credit which are then issued and
         outstanding and any activity with respect thereto which may have
         occurred since the date of the prior report, and including therein,
         among other things, the account party, the beneficiary, the face
         amount, expiry date as well as any payments or expirations which may
         have occurred. The Issuing Lender will further provide to the Agent
         promptly upon request copies of the Letters of Credit. The Issuing
         Lender will provide to the Agent prompt notice of any changes in LOC
         Obligations issued by it, and more frequently upon request, a summary
         report of the nature and extent of LOC Obligations then outstanding.

                  (c)      Participations. Each Lender, with respect to the
         Existing Letters of Credit, hereby purchases a participation interest
         in such Existing Letters of Credit and with respect to Letters of
         Credit issued on or after the Closing Date, upon issuance of a Letter
         of Credit, shall be deemed to have purchased without recourse a risk
         participation from the Issuing Lender in such Letter of Credit and the
         obligations arising thereunder and any collateral relating thereto, in
         each case in an amount equal to its LOC Commitment Percentage of the
         obligations under such Letter of Credit and shall absolutely,
         unconditionally and irrevocably assume, as primary obligor and not as
         surety, and be obligated to pay to the Issuing Lender therefor and
         discharge when due, its LOC Commitment Percentage of the obligations
         arising under such Letter of Credit. Without limiting the scope and
         nature of each Lender's participation in any Letter of Credit, to the
         extent that the Issuing Lender has not been reimbursed as required
         hereunder or under any LOC Document, each such Lender shall pay to the
         Issuing Lender its LOC Commitment Percentage of such unreimbursed
         drawing in same day funds on the day of notification by the Issuing
         Lender of an unreimbursed drawing pursuant to the provisions of
         subsection (d) hereof. The obligation of each Lender to so reimburse
         the Issuing Lender shall be absolute and unconditional and shall not be
         affected by the occurrence of a Default, an Event of Default or any
         other occurrence or event. Any such reimbursement shall not relieve or
         otherwise impair the obligation of the Borrower to reimburse the
         Issuing Lender under any Letter of Credit, together with interest as
         hereinafter provided.

                  (d)      Reimbursement. In the event of any drawing under any
         Letter of Credit, the Issuing Lender will promptly notify the Borrower
         and the Agent. The Borrower shall reimburse the Issuing Lender on the
         first Business Day following notice of payment under any Letter of
         Credit (either with the proceeds of a Revolving Loan obtained hereunder
         or otherwise) in same day funds as provided herein or in the LOC
         Documents, together with interest on the amount of such payment at the
         Prime Rate from the date of payment until the date of reimbursement.
         Unless the Borrower shall notify the Issuing Lender and the Agent on
         the date Borrower receives notice of a payment of its intent to
         otherwise reimburse the Issuing Lender, the Borrower shall be deemed to
         have requested a Revolving Loan in the amount of the payment as
         provided in subsection (e) hereof, the proceeds of which will be used
         to satisfy the reimbursement obligations. The Borrower's reimbursement
         obligations hereunder shall be absolute and unconditional under all
         circumstances irrespective of any rights of set-off, counterclaim or
         defense to payment


                                      -25-

<PAGE>   31


         the Borrower may claim or have against the Issuing Lender, the Agent,
         the Lenders, the beneficiary of the Letter of Credit drawn upon or any
         other Person, including, without limitation, any defense based on any
         failure of the Borrower to receive consideration or the legality,
         validity, regularity or unenforceability of the Letter of Credit. The
         Issuing Lender will promptly notify the other Lenders of the amount of
         any unreimbursed payment and each Lender shall promptly pay to the
         Agent for the account of the Issuing Lender in Dollars and in
         immediately available funds, the amount of such Lender's LOC Commitment
         Percentage of such unreimbursed drawing. Such payment shall be made on
         the day such notice is received by such Lender from the Issuing Lender
         if such notice is received at or before 2:00 P.M. (Milwaukee, Wisconsin
         time), otherwise such payment shall be made at or before 12:00 P.M.
         (Milwaukee, Wisconsin time) on the Business Day next succeeding the day
         such notice is received. If such Lender does not pay such amount to the
         Issuing Lender in full upon such request, such Lender shall, on demand,
         pay to the Agent for the account of the Issuing Lender interest on the
         unpaid amount during the period from the date of such payment until
         such Lender pays such amount to the Issuing Lender in full at a rate
         per annum equal to, if paid within two (2) Business Days of the date of
         such request, the Federal Funds Rate and thereafter at a rate equal to
         the Prime Rate. Each Lender's obligation to make such payment to the
         Issuing Lender, and the right of the Issuing Lender to receive the
         same, shall be absolute and unconditional, shall not be affected by any
         circumstance whatsoever and without regard to the termination of this
         Credit Agreement or the Commitments hereunder, the existence of a
         Default or Event of Default or the acceleration of the Obligations
         hereunder and shall be made without any offset, abatement, withholding
         or reduction whatsoever.

                  (e)      Repayment with Revolving Loans. On any day on which
         the Borrower shall be deemed to have requested a Revolving Loan to
         reimburse a drawing under a Letter of Credit, the Agent shall give
         notice to the Lenders that a Revolving Loan has been requested or
         deemed requested in connection with a drawing under a Letter of Credit,
         in which case a Revolving Loan borrowing comprised entirely of Prime
         Rate Loans (each such borrowing, a "Mandatory Borrowing") shall be
         immediately made (without giving effect to any termination of the
         Commitments pursuant to Section 10) pro rata based on each Lender's
         respective Revolving Commitment Percentage (determined before giving
         effect to any termination of the Commitments pursuant to Section 10)
         and in the case of both clauses (i) and (ii) the proceeds thereof shall
         be paid directly to the Issuing Lender for application to the
         respective LOC Obligations. Each Lender hereby irrevocably agrees to
         make such Revolving Loans immediately upon any such request or deemed
         request on account of each Mandatory Borrowing in the amount and in the
         manner specified in the preceding sentence and on the same such date
         notwithstanding (i) the amount of Mandatory Borrowing may not comply
         with the minimum amount for borrowings of Revolving Loans otherwise
         required hereunder, (ii) whether any conditions specified in Section
         5.2 are then satisfied, (iii) whether a Default or an Event of Default
         then exists, (iv) failure for any such request or deemed request for
         Revolving Loan to be made by the time otherwise required in Section
         3.1(b), (v) the date of such Mandatory Borrowing, or (vi) any reduction
         in the Revolving Committed Amount after any such Letter of Credit may
         have been drawn upon; provided, however, that in the event any such
         Mandatory Borrowing should be less than the minimum amount for
         borrowings of Revolving Loans otherwise provided in Section 3.1(b)(ii),
         the Borrower


                                      -26-

<PAGE>   32


         shall pay to the Agent for its own account an administrative fee of
         $500. In the event that any Mandatory Borrowing cannot for any reason
         be made on the date otherwise required above (including, without
         limitation, as a result of the commencement of a proceeding under the
         Bankruptcy Code with respect to the Borrower), then each such Lender
         hereby agrees that it shall forthwith fund (as of the date the
         Mandatory Borrowing would otherwise have occurred, but adjusted for any
         payments received from the Borrower on or after such date and prior to
         such purchase) its Participation Interests in the outstanding LOC
         Obligations; provided, further, that in the event any Lender shall fail
         to fund its Participation Interest on the day the Mandatory Borrowing
         would otherwise have occurred, then the amount of such Lender's
         unfunded Participation Interest therein shall bear interest payable to
         the Issuing Lender upon demand, at the rate equal to, if paid within
         two (2) Business Days of any such request, the Federal Funds Rate, and
         thereafter at a rate equal to the Prime Rate.

                  (f)      Modification, Extension. The issuance of any
         supplement, modification, amendment, renewal, or extension to any
         Letter of Credit shall, solely for purposes of this Agreement, be
         treated in all respects the same as the issuance of a new Letter of
         Credit, but without duplication in computing the aggregate outstanding
         amount of LOC Obligations.

                  (g)      Uniform Customs and Practices. The Issuing Lender
         shall have the Letters of Credit be subject to The Uniform Customs and
         Practice for Documentary Credits, as published as of the date of issue
         by the International Chamber of Commerce (the "UCP"), in which case the
         UCP may be incorporated therein and deemed in all respects to be a part
         thereof, with such exceptions thereto as the beneficiary may request
         and the Issuing Lender and account party may approve.

         3.3      Term Loan.

                  (a)      Term Loan. Subject to and upon the terms and
         conditions hereof, each Lender severally agrees to make its Term Loan
         Commitment Percentage of a term loan (the "Term Loan") to the Borrower
         on the Closing Date in the aggregate principal amount of TWENTY-FIVE
         MILLION DOLLARS ($25,000,000) for the purposes hereinafter set forth.
         The Term Loan may consist of Prime Rate Loans or Eurodollar Loans, or a
         combination thereof, as the Borrower may request. Amounts repaid on the
         Term Loan may not be reborrowed. Each Lender will make its Term Loan
         Commitment Percentage of each Term Loan advance available to the Agent
         on the Closing Date. Eurodollar Loans shall be made by each Lender at
         its Eurodollar Lending Office and Prime Rate Loans at its Domestic
         Lending Office. In the event the Borrower shall fail to borrow the
         entire Term Loan Committed Amount, the schedule amortization payments
         required under Section 3.3(b) shall be reduced in inverse order of
         maturity by the amount of the difference.

                  (b)      Repayment of the Term Loan. The principal amount of
         the Term Loan shall be repaid in quarterly payments of $416,666 each,
         commencing on September 30, 2001 and on the last day of each September,
         December, March and June thereafter, with a

                                      -27-


<PAGE>   33


         final principal payment of $17,083,346 (together with all accrued but
         unpaid interest) on the Term Termination Date.

                  (c)      Interest on the Term Loan. Subject to the provisions
         of Section 4.1, the Term Loan shall bear interest as follows:

                           (i)      Prime Rate Loans. During such periods as the
                  Term Loan shall be comprised of Prime Rate Loans, each such
                  Prime Rate Loan shall bear interest at a per annum rate equal
                  to the Prime Rate; and

                           (ii)     Eurodollar Loans. During such periods as the
                  Term Loan shall be comprised of Eurodollar Loans, each such
                  Eurodollar Loan shall bear interest at a per annum rate equal
                  to the sum of the applicable Eurodollar Rate plus the
                  Applicable Percentage as of the commencement of the Interest
                  Period applicable thereto.

         Interest on the Term Loan shall be payable in arrears on each Interest
         Payment Date.

                  (d)      Term Notes. The Term Loan shall be evidenced by a
         duly executed promissory note of the Borrower to each Lender in the
         original principal amount of each such Lender's Term Loan Committed
         Amount in substantially the form of Exhibit 3.3(d).

                                   ARTICLE 4

                 OTHER PROVISIONS RELATING TO CREDIT FACILITIES

         4.1      Default Rate. Upon the occurrence, and during the continuance,
of an Event of Default, the principal of and, to the extent permitted by law,
interest on the Loans and any other amounts owing hereunder or under the other
Credit Documents shall bear interest, payable on demand, at a per annum rate
which is equal to the rate which would otherwise be applicable (or if no rate is
applicable, whether in respect of interest, fees or other amounts, then the
Prime Rate) plus 2%.

         4.2      Extension and Conversion. The Borrower shall have the option,
on any Business Day, to extend existing Loans into a subsequent permissible
Interest Period or to convert Loans into Loans of another Type; provided,
however, that (i) except as provided in Section 4.7, Eurodollar Loans may be
converted into Prime Rate Loans only on the last day of the Interest Period
applicable thereto, (ii) Eurodollar Loans may be extended, and Prime Rate Loans
may be converted into Eurodollar Loans, only if no Default or Event of Default
is in existence on the date of extension or conversion, (iii) Loans extended as,
or converted into, Eurodollar Loans shall be subject to the terms of the
definition of "Interest Period" set forth in Section 2.1 and shall be in such
minimum amounts as provided in Section 3.1(b)(ii) and (iv) any request for
extension or conversion of a Eurodollar Loan which shall fail to specify an
Interest Period shall be deemed to be a request for an Interest Period of one
month. Each such extension or conversion shall be effected by the Borrower by
giving a Notice of Extension/Conversion in the form of Exhibit 4.2 (or telephone
notice promptly confirmed in writing) to the Agent prior to 10:30 A.M.
(Milwaukee, Wisconsin time) on the Business Day of, in the case of the
conversion of a Eurodollar Loan into a Prime Rate Loan and on the third Business
Day prior to, in the case


                                      -28-

<PAGE>   34


of the extension of a Eurodollar Loan as, or conversion of a Prime Rate Loan
into, a Eurodollar Loan, the date of the proposed extension or conversion,
specifying the date of the proposed extension or conversion, the Loans to be so
extended or converted, the Types of Loans into which such Loans are to be
converted and, if appropriate, the applicable Interest Periods with respect
thereto. Each request for extension or conversion shall constitute a
representation and warranty by the Borrower of the matters specified in
paragraphs (a) and (b), and in (c) or (d), of Section 6.2. In the event the
Borrower fails to request extension or conversion of any Eurodollar Loan in
accordance with this Section, or any such conversion or extension is not
permitted or required by this Section, then such Loans shall be automatically
converted into Prime Rate Loans at the end of their Interest Period. The Agent
shall give each Lender notice as promptly as practicable of any such proposed
extension or conversion affecting any Loan.

         4.3      Reductions in Commitments and Prepayments.

                  (a)      Reductions in Revolving Commitment. The Borrower may
         from time to time permanently reduce the Aggregate Revolving Committed
         Amount in whole or in part without premium or penalty except as
         provided in Section 4.10 upon three (3) Business Days' prior written
         notice to the Agent; provided that after giving effect to any such
         voluntary reduction the sum of Revolving Loans plus LOC Obligations
         then outstanding shall not exceed the Aggregate Revolving Committed
         Amount, as reduced. Except as otherwise specified herein, partial
         reductions in the Aggregate Revolving Committed Amount shall in each
         case be in a minimum aggregate amount of $1,000,000 and integral
         multiples of $1,000,000 in excess thereof.

                  (b)      Mandatory Prepayment on Revolving Loans. If at any
         time the sum of the aggregate amount of Revolving Loans plus LOC
         Obligations then outstanding shall exceed the Aggregate Revolving
         Committed Amount, as reduced from time to time, the Borrower shall
         immediately make payment on the Revolving Loans and then, if necessary,
         to a cash collateral account in respect of the LOC Obligations, in an
         amount sufficient to eliminate the deficiency. Any such payments shall
         be applied first to Prime Rate Loans and then to Eurodollar Loans in
         direct order of their Interest Period maturities.

                  (c)      Voluntary Prepayments. Loans may be prepaid in whole
         or in part without premium or penalty except as provided in Section
         4.10. Any partial prepayment shall be in a minimum aggregate principal
         amount of $1,000,000 and integral multiples of $500,000 in excess
         thereof. Except as otherwise specified herein, amounts prepaid on the
         Revolving Loans may be reborrowed in accordance with the provisions
         hereof. Amounts prepaid on the Term Loan shall be applied in inverse
         order of maturity to the payments of principal due pursuant to Section
         3.3(b). Amounts prepaid on the Term Loan may not be reborrowed.

         4.4      Fees.

                  (a)      Letter of Credit Fee. In consideration of the
         issuance of Letters of Credit hereunder, the Borrower agrees to pay to
         the Agent for the ratable benefit of the Lenders a fee with respect to
         each Letter of Credit (the "Letter of Credit Fee") equal to the


                                      -29-

<PAGE>   35


         Applicable Percentage per annum on the average daily maximum amount
         available to be drawn under such Letter of Credit from the date of
         issuance calculated for the term of availability thereof. The Letter of
         Credit Fee shall be payable quarterly in arrears with respect to each
         Letter of Credit on the last day of each calendar quarter and on the
         Revolving Termination Date and shall be in lieu of any other fees in
         connection with the issuance of Letters of Credit hereunder, except for
         such standard and customary fees, costs and expenses incurred or
         charged by the Issuing Lender in issuing, effecting payment under,
         amending or otherwise administering any Letter of Credit as the
         Borrower and the Issuing Lender may mutually agree.

                  (b)      Commitment Fee. In consideration of the Commitments
         by the Lenders hereunder, the Borrower agrees to pay to the Agent for
         the ratable benefit of the Lenders a commitment fee (the "Commitment
         Fee") in an amount equal to $162,500. The Commitment Fee shall be fully
         earned and payable on the Closing Date.

                  (c)      Administrative Fees. The Borrower agrees to pay to
         the Agent, for its own account, an administrative and structuring fee
         (the "Agent's Fee") referred to in that certain Agent's fee letter
         dated March 15, 2001. The Agent's Fee shall be fully earned and payable
         on the Closing Date.

                  (d)      Non-Use Fee. The Borrower shall pay to the Agent for
         the account of each Lender a non-use fee (the "Non-Use Fee") equal to
         the Applicable Percentage per annum on the average daily unused portion
         of such Lender's Commitment, computed on a quarterly basis in arrears
         on the last Business Day of each March, June, September and December
         commencing on June 30, 2001. The non-use fees provided in this Section
         4.4(d) shall accrue at all times after the above-mentioned commencement
         date, including at any time during which one or more conditions in
         Article V are not met.

         4.5      Capital Adequacy. If any Lender has reasonably determined that
the adoption or effectiveness of any applicable law, rule or regulation
regarding capital adequacy made after the date hereof, or any change therein
made after the date hereof, or any change in the interpretation or
administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof made after the
date hereof, or compliance by such Lender or its parent company with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency made after the date
hereof, has or would have the effect of reducing the rate of return on such
Lender's or its parent company's capital or assets as a consequence of its
commitments or obligations hereunder to a level below that which such Lender
could have achieved but for such adoption, effectiveness, change or compliance
(taking into consideration the policies of such Lender and its parent company
with respect to capital adequacy), then, within 10 Business Days after the
Borrower's receipt of the certificate referred to in the next sentence, the
Borrower shall pay to such Lender such additional amount or amounts as will
compensate such Lender and its parent company for such reduction; provided that
no such amounts shall be payable with respect to reduction in rate of return
incurred more than three (3) months before such Lender demands compensation
under this Section 4.5. A certificate as to the amount of such reduction in rate
of return, the good faith basis therefor and setting forth in reasonable detail
the calculations used by the applicable Lender to arrive at the amount or


                                      -30-

<PAGE>   36


amounts claimed to be due, shall be submitted to the Borrower and the Agent.
Each determination by a Lender of amounts owing under this Section shall be
rebuttably presumptive evidence of the matters set forth therein. No demand for
payment under this Section shall be made unless the Lender shall make comparable
demands of other similarly situated borrowers. The provisions of this Section
shall survive termination of this Credit Agreement and the payment of the Loans
and all other amounts payable hereunder.

         4.6      Inability To Determine Interest Rate. If prior to the first
day of any Interest Period, the Agent shall have reasonably determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the relevant market, adequate and reasonable means do
not exist for ascertaining the Eurodollar Rate for such Interest Period, the
Agent shall give telecopy or telephonic notice thereof to the Borrower and the
Lenders as soon as practicable thereafter. If such notice is given (a) any
Eurodollar Loans requested to be made on the first day of such Interest Period
shall be made as Prime Rate Loans, (b) any Loans that were to have been
converted on the first day of such Interest Period to or continued as Eurodollar
Loans shall be converted to or continued as Prime Rate Loans and (c) any
outstanding Eurodollar Loans shall be converted, on the first day of such
Interest Period, to Prime Rate Loans. Until such notice has been withdrawn by
the Agent, no further Eurodollar Loans shall be made or continued as such, nor
shall the Borrower have the right to convert Prime Rate Loans to Eurodollar
Loans.

         4.7      Illegality. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof occurring after the Closing Date shall make it unlawful for
any Lender to make or maintain Eurodollar Loans as contemplated by this Credit
Agreement, (a) such Lender shall promptly give written notice of such
circumstances to the Borrower and the Agent (which notice shall be withdrawn
whenever such circumstances no longer exist), (b) the commitment of such Lender
hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert a Prime Rate Loan to Eurodollar Loans shall forthwith be canceled and,
until such time as it shall no longer be unlawful for such Lender to make or
maintain Eurodollar Loans, such Lender shall then have a commitment only to make
a Prime Rate Loan when a Eurodollar Loan is requested and (c) such Lender's
Loans then outstanding as Eurodollar Loans, if any, shall be converted
automatically to Prime Rate Loans on the respective last days of the then
current Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to Section 4.10.

         4.8      Requirements of Law. If the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof applicable to
any Lender, or compliance by any Lender with any request or directive (whether
or not having the force of law) from any central bank or other Governmental
Authority, in each case made subsequent to the Closing Date (or, if later, the
date on which such Lender becomes a Lender):

                           (i)      shall subject such Lender to any tax of any
                  kind whatsoever on or in respect of any Letter of Credit,
                  letter of credit application or any Eurodollar Loans made by
                  it or its obligation to make Eurodollar Loans, or change the
                  basis


                                      -31-

<PAGE>   37


                  of taxation of payments to such Lender in respect thereof
                  except for Non-Excluded Taxes covered by Section 4.9
                  (including Non-Excluded Taxes imposed solely by reason of any
                  failure of such Lender to comply with its obligations under
                  Section 4.9(b)) and changes in taxes measured by or imposed
                  upon the overall net income, or franchise tax (imposed in lieu
                  of such net income tax), of such Lender or its applicable
                  lending office, branch, or any affiliate thereof); or

                           (ii)     shall impose, modify or hold applicable any
                  reserve, special deposit, compulsory loan or similar condition
                  or requirement against assets held by, deposits or other
                  liabilities in or for the account of, advances, loans or other
                  extensions of credit by, or any other acquisition of funds by,
                  any office of such Lender which is not otherwise included in
                  the determination of the Eurodollar Rate hereunder;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, upon notice to the
Borrower from such Lender, through the Agent, in accordance herewith, the
Borrower shall promptly pay such Lender, upon its demand, any additional amounts
necessary to compensate such Lender for such increased cost or reduced amount
receivable, provided that, in any such case, the Borrower may elect to convert
the Eurodollar Loans made by such Lender hereunder to Prime Rate Loans by giving
the Agent at least one Business Day's notice of such election, in which case the
Borrower shall promptly pay to such Lender, upon demand, without duplication,
such amounts, if any, as may be required pursuant to Section 4.10. If any Lender
becomes entitled to claim any additional amounts pursuant to this subsection, it
shall provide prompt notice thereof to the Borrower, through the Agent,
certifying (a) that one of the events described in this Section 4.8 has occurred
and describing in reasonable detail the nature of such event, (b) as to the
increased cost or reduced amount resulting from such event and (c) as to the
additional amount demanded by such Lender and a reasonably detailed explanation
of the calculation thereof. Such a certificate as to any additional amounts
payable pursuant to this subsection shall be submitted by such Lender, through
the Agent, to the Borrower and shall be conclusive in the absence of manifest
error. No demand for payment under this Section shall be made unless the Lender
shall make comparable demands of other similarly situated borrowers. This
covenant shall survive the termination of this Credit Agreement and the payment
of the Loans and all other amounts payable hereunder.

         4.9      Taxes.

                  (a)      Except as provided below in this subsection, all
         payments made by the Borrower under this Credit Agreement and any Notes
         shall be made free and clear of, and without deduction or withholding
         for or on account of, any present or future income, stamp or other
         taxes, levies, imposts, duties, charges, fees, deductions or
         withholdings, now or hereafter imposed, levied, collected, withheld or
         assessed by any Governmental Authority, excluding taxes measured by or
         imposed upon the overall net income of any Lender or its applicable
         lending office, or any branch or affiliate thereof, and all franchise
         taxes, branch taxes, taxes on doing business or taxes on the overall
         capital or net worth of any Lender or its applicable lending office, or
         any branch or affiliate thereof, in each case


                                      -32-

<PAGE>   38


         imposed in lieu of net income taxes, imposed: (i) by the jurisdiction
         under the laws of which such Lender, applicable lending office, branch
         or affiliate is organized or is located, or in which its principal
         executive office is located, or any nation within which such
         jurisdiction is located or any political subdivision thereof; or (ii)
         by reason of any connection between the jurisdiction imposing such tax
         and such Lender, applicable lending office, branch or affiliate other
         than a connection arising solely from such Lender having executed,
         delivered or performed its obligations, or received payment under or
         enforced, this Credit Agreement or any Notes. If any such non-excluded
         taxes, levies, imposts, duties, charges, fees, deductions or
         withholdings ("Non-Excluded Taxes") are required to be withheld from
         any amounts payable to the Agent or any Lender hereunder or under any
         Notes, (A) the amounts so payable to the Agent or such Lender shall be
         increased to the extent necessary to yield to the Agent or such Lender
         (after payment of all Non-Excluded Taxes) interest or any such other
         amounts payable hereunder at the rates or in the amounts specified in
         this Credit Agreement and any Notes, provided, however, that the
         Borrower shall be entitled to deduct and withhold any Non-Excluded
         Taxes and shall not be required to increase any such amounts payable to
         any Lender that is not organized under the laws of the United States of
         America or a state thereof if such Lender fails to comply with the
         requirements of paragraph (b) of this subsection whenever any
         Non-Excluded Taxes are payable by the Borrower, and (B) as promptly as
         possible thereafter the Borrower shall send to the Agent for its own
         account or for the account of such Lender, as the case may be, a
         certified copy of an original official receipt received by the Borrower
         showing payment thereof. If the Borrower fails to pay any Non-Excluded
         Taxes when due to the appropriate taxing authority or fails to remit to
         the Agent the required receipts or other required documentary evidence,
         the Borrower shall indemnify the Agent and the Lenders for any
         incremental taxes, interest or penalties that may become payable by the
         Agent or any Lender as a result of any such failure. The agreements in
         this subsection shall survive the termination of this Credit Agreement
         and the payment of the Loans and all other amounts payable hereunder.

                  (b)      At least five Business Days prior to the first day on
         which interest or Fees are payable hereunder for the account of any
         Lender, each Lender that is not incorporated under the laws of the
         United States of America, or a state thereof, agrees that it will
         deliver to each of the Borrower and the Agent two duly completed copies
         of United States Internal Revenue Service Form 1001 or 4224, certifying
         in either case that such Lender is entitled to receive payments under
         this Agreement and the Notes without deduction or withholding of any
         United States federal income taxes. Each Lender which so delivers a
         Form 1001 or 4224 further undertakes to deliver to each of the Borrower
         and the Agent two additional copies of such form (or a successor form)
         on or before the date that such form expires (currently, three
         successive calendar years for Form 1001 and one calendar year for Form
         4224) or becomes obsolete or after the occurrence of any event
         requiring a change in the most recent forms so delivered by it, and
         such amendments thereto or extensions or renewals thereof as may be
         reasonably requested by the Borrower or the Agent, in each case
         certifying that such Lender is entitled to receive payments under this
         Credit Agreement and the Notes without deduction or withholding of any
         United States federal income taxes, unless an event (including, without
         limitation, any change in treaty, law or regulation) has occurred prior
         to the date on which any such delivery would otherwise be required
         which renders all such forms inapplicable or which

                                      -33-


<PAGE>   39


         would prevent such Lender from duly completing and delivering any such
         form with respect to it and such Lender advises the Borrower and the
         Agent that it is not capable of receiving payments without any
         deductions or withholding of United States federal income tax.

         4.10     Indemnity. The Borrower agrees to indemnify each Lender and to
hold each Lender harmless from any loss or expense which such Lender may sustain
or incur (other than through such Lender's gross negligence or willful
misconduct) as a consequence of (a) default by the Borrower in making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Credit Agreement, (b) default by the Borrower in making any
prepayment of a Eurodollar Loan after the Borrower has given a notice thereof in
accordance with the provisions of this Credit Agreement or (c) the making of a
prepayment of Eurodollar Loans on a day which is not the last day of an Interest
Period with respect thereto. Such indemnification may include an amount equal to
the excess, if any, of (i) the amount of interest which would have accrued on
the amount so prepaid, or not so borrowed, converted or continued, for the
period from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of the applicable Interest Period (or, in the case of a
failure to borrow, convert or continue, the Interest Period that would have
commenced on the date of such failure) in each case at the applicable rate of
interest for such Eurodollar Loans provided for herein over (ii) the amount of
interest (as reasonably determined by such Lender) which would have accrued to
such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank Eurodollar market, provided, however,
that the amount of such lost interest, if any, shall be discounted to a present
value as of the date of the indemnification payment, using as the applicable
discount rate(s) the rate(s) of per annum interest used by such Lender in making
the computations pursuant to the foregoing clause (ii). This covenant shall
survive the termination of this Credit Agreement and the payment of the Loans
and all other amounts payable hereunder.

         4.11     Pro Rata Treatment. Except to the extent otherwise provided
herein:

                  (a)      Loans. Each Loan, each payment or prepayment of
         principal of any Loan, each payment of interest on the Loans, each
         payment of Fees (other than the Fee to the Agent pursuant to Section
         4.4(c)), each reduction of the Revolving Committed Amount and each
         conversion or extension of any Loan, shall be allocated pro rata among
         the Lenders in accordance with the respective Commitment Percentages
         relating to such respective Loans and Participation Interests.

                  (b)      Advances. Unless the Agent shall have been notified
         in writing by any Lender prior to a borrowing that such Lender will not
         make the amount that would constitute its Commitment Percentage of such
         borrowing available to the Agent, the Agent may assume that such Lender
         is making such amount available to the Agent, and the Agent may, in
         reliance upon such assumption, make available to the Borrower a
         corresponding amount. If such amount is not made available to the Agent
         by such Lender within the time period specified therefor hereunder,
         such Lender shall pay to the Agent, on demand, such amount with
         interest thereon at a rate equal to the Federal Funds Rate for the
         period until such Lender makes such amount immediately available to the
         Agent. A certificate of the Agent submitted to any Lender with respect
         to any amounts

         owing under this subsection shall be conclusive in the absence of
         manifest error. If such Lender's Commitment Percentage of such
         borrowing is not made available to the Agent by such Lender within two
         business Days of the date of the related borrowing, (i) the Agent shall
         notify the Borrower of the failure of such Lender to make such amount
         available to the Agent and the Agent shall also be entitled to recover
         such amount with interest thereon at the rate per annum applicable to
         Prime Rate Loans hereunder, on demand, from the Borrower and (ii) then
         the Borrower may, without waiving any rights it may have against such
         Lender, (x) request the Lender serving as Agent to increase its
         Revolving Commitment Percentage and make such borrowing available,
         which request such Lender may in its sole discretion approve or deny,
         and (y) if the Lender serving as Agent shall deny a request submitted
         to it pursuant to the foregoing clause (x), borrow a like amount on an
         unsecured basis from any commercial bank for a period ending on the
         date upon which such Lender does in fact make such borrowing available;
         provided, however, that at the time any such replacement borrowing is
         made and at all times while such amount is outstanding the Borrower
         would be permitted to borrow such amount pursuant to Section 3.1 of
         this Credit Agreement.

         4.12     Sharing of Payments. The Lenders agree among themselves that,
in the event that any Lender shall obtain payment in respect of any Loan or any
other obligation owing to such Lender under this Credit Agreement through the
exercise of a right of setoff, banker's lien or counterclaim, or pursuant to a
secured claim under Section 506 of Title 11 of the United States Code or other
security or interest arising from, or in lieu of, such secured claim, received
by such Lender under any applicable bankruptcy, insolvency or other similar law
or otherwise, or by any other means, in excess of its pro rata share of such
payment as provided for in this Credit Agreement, such Lender shall promptly
purchase from the other Lenders a participation in such Loans and other
obligations in such amounts, and make such other adjustments from time to time,
as shall be equitable to the end that all Lenders share such payment in
accordance with their respective ratable shares as provided for in this Credit
Agreement. The Lenders further agree among themselves that if payment to a
Lender obtained by such Lender through the exercise of a right of setoff,
banker's lien, counterclaim or other event as aforesaid shall be rescinded or
must otherwise be restored, each Lender which shall have shared the benefit of
such payment shall, by repurchase of a participation theretofore sold, return
its share of that benefit (together with its share of any accrued interest
payable with respect thereto) to each Lender whose payment shall have been
rescinded or otherwise restored. The Borrower agrees that any Lender so
purchasing such a participation may, to the fullest extent permitted by law,
exercise all rights of payment, including setoff, banker's lien or counterclaim,
with respect to such participation as fully as if such Lender were a holder of
such Loan or other obligation in the amount of such participation. Except as
otherwise expressly provided in this Credit Agreement, if any Lender or the
Agent shall fail to remit to the Agent or any other Lender an amount payable by
such Lender or the Agent to the Agent or such other Lender pursuant to this
Credit Agreement on the date when such amount is due, such payments shall be
made together with interest thereon for each date from the date such amount is
due until the date such amount is paid to the Agent or such other Lender at a
rate per annum equal to the Federal Funds Rate. If under any applicable
bankruptcy, insolvency or other similar law, any Lender receives a secured claim
in lieu of a setoff to which this Section 4.12 applies, such Lender shall, to
the extent practicable, exercise its rights in respect of such secured claim in
a manner consistent with the rights of the Lenders under this Section 4.12 to
share in the benefits of any recovery on such secured claim.

         4.13     Place and Manner of Payments. Except as otherwise specifically
provided herein, all payments hereunder shall be made to the Agent in Dollars in
immediately available funds, without offset, deduction, counterclaim or
withholding of any kind, at its offices at the Agent's office specified in
Schedule 12.2 not later than 1:00 P.M. (Milwaukee, Wisconsin time) on the date
when due. Payments received after such time shall be deemed to have been
received on the next succeeding Business Day. The Agent may, at the Borrower's
request, debit the amount of any such payment which is not made by such time to
Account No. 121581139 maintained by the Borrower with the Agent or any other
account which may be maintained by the Borrower with the Agent and designated
for such purpose by the Borrower. The Borrower shall, at the time it makes any
payment under this Credit Agreement, specify to the Agent the Loans, Fees or
other amounts payable by the Borrower hereunder to which such payment is to be
applied (and in the event that it fails so to specify, or if such application
would be inconsistent with the terms hereof, the Agent shall distribute such
payment to the Lenders in such manner as the Agent may determine to be
appropriate in respect of obligations owing by the Borrower hereunder, subject
to the terms of Section 4.11). The Agent will distribute such payments to such
Lenders, if any such payment is received prior to 1:00 p.m. (Milwaukee,
Wisconsin time) on a Business Day in like funds as received prior to the end of
such Business Day and otherwise the Agent will distribute such payment to such
Lenders on the next succeeding Business Day. Whenever any payment hereunder
shall be stated to be due on a day which is not a Business Day, the due date
thereof shall be extended to the next succeeding Business Day (subject to
accrual of interest and Fees for the period of such extension), except that in
the case of Eurodollar Loans, if the extension would cause the payment to be
made in the next following calendar month, then such payment shall instead be
made on the next preceding Business Day. Except as expressly provided otherwise
herein, all computations of interest and fees shall be made on the basis of
actual number of days elapsed over a year of 360 days. Interest shall accrue
from and include the date of borrowing, but exclude the date of payment.

         4.14     Indemnification: Nature of Issuing Lender's Duties.

                  (a)      In addition to its other obligations under Section
         3.2, the Borrower hereby agrees to protect, indemnify, pay and save
         each Issuing Lender harmless from and against any and all claims,
         demands, liabilities, damages, losses, costs, charges and expenses
         (including reasonable attorneys' fees) that the Issuing Lender may
         incur or be subject to as a consequence, direct or indirect, of (A) the
         issuance of any Letter of Credit or (B) the failure of the Issuing
         Lender to honor a drawing under a Letter of Credit as a result of any
         act or omission, whether rightful or wrongful, of any present or future
         de jure or de facto government or Governmental Authority (all such acts
         or omissions, herein called "Government Acts").

                  (b)      As between the Borrower and the Issuing Lender, the
         Borrower shall assume all risks of the acts, omissions or misuse of any
         Letter of Credit by the beneficiary thereof. The Issuing Lender shall
         not be responsible: (i) for the form, validity, sufficiency, accuracy,
         genuineness or legal effect of any document submitted by any party in
         connection with the application for and issuance of any Letter of
         Credit, even if it should in fact prove to be in any or all respects
         invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the
         validity or sufficiency of any instrument transferring or assigning or
         purporting to transfer or assign any Letter of Credit or the rights or
         benefits


                                      -36-

<PAGE>   42


         thereunder or proceeds thereof, in whole or in part, that may prove to
         be invalid or ineffective for any reason; (iii) for failure of the
         beneficiary of a Letter of Credit to comply fully with conditions
         required in order to draw upon a Letter of Credit; (iv) for errors,
         omissions, interruptions or delays in transmission or delivery of any
         messages, by mail, cable, telegraph, telex or otherwise, whether or not
         they be in cipher; (v) for errors in interpretation of technical terms;
         (vi) for any loss or delay in the transmission or otherwise of any
         document required in order to make a drawing under a Letter of Credit
         or of the proceeds thereof; and (vii) for any consequences arising from
         causes beyond the control of the Issuing Lender, including, without
         limitation, any Government Acts. None of the above shall affect,
         impair, or prevent the vesting of the Issuing Lender's rights or powers
         hereunder.

                  (c)      In furtherance and extension and not in limitation of
         the specific provisions hereinabove set forth, any action taken or
         omitted by the Issuing Lender, under or in connection with any Letter
         of Credit or the related certificates, if taken or omitted in good
         faith, shall not put such Issuing Lender under any resulting liability
         to the Borrower. It is the intention of the parties that this Credit
         Agreement shall be construed and applied to protect and indemnify the
         Issuing Lender against any and all risks involved in the issuance of
         the Letters of Credit, all of which risks are hereby assumed by the
         Borrower, including, without limitation, any and all risks of the acts
         or omissions, whether rightful or wrongful, of any present or future
         Government Acts. The Issuing Lender shall not, in any way, be liable
         for any failure by the Issuing Lender or anyone else to pay any drawing
         under any Letter of Credit as a result of any Government Acts or any
         other cause beyond the control of the Issuing Lender.

                  (d)      Nothing in this Section 4.14 is intended to limit the
         reimbursement obligation of the Borrower contained in Section 3.2(d)
         hereof. The obligations of the Borrower under this Section 4.14 shall
         survive the termination of this Agreement. No act or omissions of any
         current or prior beneficiary of a Letter of Credit shall in any way
         affect or impair the rights of the Issuing Lender to enforce any right,
         power or benefit under this Credit Agreement.

                  (e)      Notwithstanding anything to the contrary contained in
         this Section 4.14, the Borrower shall have no obligation to indemnify
         any Issuing Lender in respect of any liability incurred by such Issuing
         Lender arising out of the gross negligence or willful misconduct of the
         Issuing Lender (including action not taken by an Issuing Lender) or to
         reimburse the Issuing Lender for payments made by such Issuing Lender
         on a Letter of Credit with respect to which the drafts and accompanying
         documents do not reasonably appear to comply with the terms of the
         Letter of Credit, as determined by a court of competent jurisdiction.

         4.15     Transfers at Borrower's Request. In the event that any Lender
requests payment by the Borrower of any additional amounts pursuant to Section
4.5, 4.7, 4.8 or 4.9, then, provided that no Default or Event of Default has
occurred and is continuing at such time, the Borrower may, at its own expense
(such expense to include any transfer fee payable to the Agent under Section
12.6(b)), and in its sole discretion require such Lender to transfer and assign
in whole or in part, without recourse (in accordance with and subject to the
terms and conditions of


                                      -37-

<PAGE>   43


Section 12.6(b)), all or part of its interests, rights and obligations under
this Credit Agreement to an Eligible Transferee which shall assume such assigned
obligations; provided that (i) the other Lenders may, by written notice to the
Agent, the Lenders and the Borrower, in their respective discretion, elect to
assume such Lender's Revolving Commitment, LOC Commitment and Term Loan
Commitment, pro rata based upon the respective Revolving Commitment Percentages
and Term Loan Commitment Percentages of the other Lenders so electing to assume
such Lender's Commitments hereunder, (ii) such Eligible Transferee which is not
a Lender shall be reasonably acceptable to the Required Lenders, (iii) such
assignment shall not relieve the Borrower from its obligations to pay such
additional amounts that may be due in accordance with Section 4.5, 4.7, 4.8 or
4.9, (iv) such assignment shall not conflict with any law, rule or regulation or
order of any court or other Governmental Authority and (v) the Borrower or such
Eligible Transferee shall have paid to the assigning Lender in immediately
available funds the principal of and interest accrued to the date of such
payment on the Loans made by it hereunder and all accrued Fees and other amounts
owed to it hereunder.

                                   ARTICLE 5

                                    GUARANTY

         5.1      The Guaranty. Each of the Credit Parties hereby jointly and
severally guarantees to each Lender, the Agent and the Issuing Lender as
hereinafter provided the prompt payment of the Credit Party Obligations in full
when due (whether at stated maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise) strictly in
accordance with the terms thereof. The Credit Parties hereby further agree that
if any of the Credit Party Obligations are not paid in full when due (whether at
stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash
collateralization or otherwise), the Credit Parties will, jointly and severally,
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Credit Party
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, as a mandatory prepayment, by acceleration, as a mandatory
cash collateralization or otherwise) in accordance with the terms of such
extension or renewal.

Notwithstanding any provision to the contrary contained herein or in any other
of the Credit Documents, the obligations of each Credit Party hereunder shall be
limited to an aggregate amount equal to the largest amount that would not render
its obligations hereunder subject to avoidance under Section 548 of the U.S.
Bankruptcy Code or any comparable provisions of any applicable state law.

         5.2      Obligations Unconditional. The obligations of the Credit
Parties under Section 5.1 hereof are joint and several, absolute and
unconditional, irrespective of the value, genuineness, validity or
enforceability of any of the Credit Documents, or any other agreement or
instrument referred to therein, or any substitution, release or exchange of any
other guarantee of or security for any of the Credit Party Obligations, and, to
the fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever which might otherwise constitute a legal or equitable
discharge or defense of a surety or guarantor, it being the intent of this
Section 5.2 that the obligations of the Credit Parties hereunder shall be
absolute and unconditional under any and all circumstances other than
indefeasible payment in full. Without


                                      -38-

<PAGE>   44


limiting the generality of the foregoing, it is agreed that the occurrence of
any one or more of the following shall not alter or impair the liability of any
Credit Party hereunder which shall remain absolute and unconditional as
described above:

                           (i)      at any time or from time to time, without
                  notice to any Credit Party, the time for any performance of or
                  compliance with any of the Credit Party Obligations shall be
                  extended, or such performance or compliance shall be waived;

                           (ii)     any of the acts mentioned in any of the
                  provisions of any of the Credit Documents or any other
                  agreement or instrument referred therein shall be done or
                  omitted;

                           (iii)    the maturity of any of the Credit Party
                  Obligations shall be accelerated, or any of the Credit Party
                  Obligations shall be modified, supplemented or amended in any
                  respect, or any right under any of the Credit Documents or any
                  other agreement or instrument referred to therein shall be
                  waived or any other guarantee of any of the Credit Party
                  Obligations or any security therefor shall be released or
                  exchanged in whole or in part or otherwise dealt with;

                           (iv)     any Lien granted to, or in favor of, the
                  Agent or any Lender or Lenders as security for any of the
                  Credit Party Obligations shall fail to attach or be perfected;
                  or

                           (v)      any of the Credit Party Obligations shall be
                  determined to be void or voidable (including, without
                  limitation, for the benefit of any creditor of any Credit
                  Party) or shall be subordinated to the claims of any Person
                  (including, without limitation, any creditor of any Credit
                  Party).

With respect to its obligations hereunder, each Credit Party hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Agent or any Lender exhaust any right,
power or remedy or proceed against any Person under any of the Credit Documents
or any other agreement or instrument referred to therein, or against any other
Person under any other guarantee of, or security for, any of the Credit Party
Obligations.

         5.3      Reinstatement. The obligations of the Credit Parties under
this Section 5 shall be automatically reinstated if and to the extent that for
any reason any payment by or on behalf of any Person in respect of the Credit
Party Obligations is rescinded or must be otherwise restored by any holder of
any of the Credit Party Obligations, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise, and each Credit Party agrees that it
will indemnify each of the Agent and each Lender on demand for all reasonable
costs and expenses (including, without limitation, reasonable attorneys' fees)
incurred by the Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.


                                      -39-

<PAGE>   45




         5.4      Certain Additional Waivers. Without limiting the generality of
the provisions of any other Section of this Section 5, each Credit Party further
agrees that it shall have no right of recourse to security for the Credit Party
Obligations. Each of the Credit Parties further agrees that it shall have no
right of subrogation, reimbursement or indemnity, nor any right of recourse to
security, if any, for the Credit Party Obligations until indefeasible payment in
full of all such obligations shall have been made.

         5.5      Remedies. The Credit Parties agree that, as between the Credit
Parties, on the one hand, and the Agent, the Lenders and the Issuing Lender, on
the other hand, the Credit Party Obligations may be declared to be forthwith due
(and payable as provided in Section 10 hereof and shall be deemed to have become
automatically due and payable in the circumstances provided in said Section 10)
for purposes of Section 5.1 hereof notwithstanding any stay, injunction or other
prohibition preventing such declaration (or preventing such Credit Party
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or such Credit Party
Obligations being deemed to have become automatically due and payable), such
Credit Party Obligations whether or not due and payable by any other Person)
shall forthwith become due and payable by the Credit Parties for purposes of
said Section 5.1.

         5.6      Continuing Guarantee. The guarantee in this Section 5 is a
continuing guarantee, and shall apply to all Credit Party Obligations whenever
arising.

                                   ARTICLE 6

                                   CONDITIONS

                  Authorities of the state of organization and each other state
                  in which the failure to so qualify and be in good standing
                  would have a material adverse effect on the business or
                  operations of the Borrower, the other Credit Parties or C2 in
                  such state.

         the Lenders.

                  (l)      Other Documents. The Agent shall have received such
         other approvals, opinions, documents or materials as the Agent or any

         Each request for Extension of Credit and each acceptance by the
Borrower of an Extension of Credit shall be deemed to constitute a
representation and warranty by the Borrower as of the date of such Extension of
Credit that the applicable conditions in paragraphs (a) and (b), and in (c) or
(d), as applicable, of this subsection have been satisfied.

                                   ARTICLE 7

                         REPRESENTATIONS AND WARRANTIES

         To induce the Lenders to enter into this Credit Agreement and to make
the Extensions of Credit herein provided for, each of the Credit Parties hereby
represents and warrants to the Agent and to each Lender that as of the Closing
Date, after giving effect to the Merger Transactions and the Divestiture, and at
all times thereafter (except as specifically set forth below in this Section 7):

         7.1      Financial Statements. Prior to the Closing Date the Borrower
has or will have furnished to the Lenders (a) the audited consolidated balance
sheet of C2 and its consolidated Subsidiaries as of December 31, 2000, and
related audited statements of income, shareholders' equity and cash flows for
the year ended on that date, together with an unqualified opinion thereon by
Arthur Andersen, LLP, and (b) the unaudited consolidated balance sheet of the
Borrower and its Consolidated Subsidiaries as of March 31, 2001 and related
statements of income, shareholders' equity and cash flows for the periods ended
on such date, prepared by the Borrower. Such financial statements were prepared
in accordance with GAAP consistently applied throughout the periods involved,
are correct and complete and fairly present the consolidated financial condition
of the Borrower and such Subsidiaries as of such dates and the results of their
operations for the periods ended on such dates, subject, in the case of the
unaudited interim statements, to the absence of footnotes, audit and normal
year-end adjustments. Since December 31, 2000 there has been no development or
event which has had a Material Adverse Effect.

         7.2      Ownership of Properties; Liens and Encumbrances. Each of the
Borrower and its Subsidiaries has good and marketable title to all property,
real and personal, reflected on the most recent financial statement of the
Borrower furnished to the Lenders, and all property purported to have been
acquired since the date of such financial statement, except property sold or
otherwise disposed of in the ordinary course of business subsequent to such
date; and all such property is free of any Lien except Permitted Liens. Except
as set forth on Schedule 7.2, all owned and leased buildings and equipment of
the Borrower used in the Borrower's business are in good operating condition,
repair and working order, except for ordinary wear and tear and insured losses,
and, to the Borrower's knowledge, conform to all applicable laws, ordinances and
regulations the violation of which would have a Material Adverse Effect. The
Borrower possesses adequate trademarks, trade names, copyrights, patents,
service marks and licenses, or rights thereto, for the present and planned
future conduct of its business substantially as now conducted, without any known
conflict with the rights of others which would result in a Material Adverse
Effect.

         7.3      Corporate Existence; Compliance with Law. Each of the Borrower
and its Subsidiaries (a) is duly organized, validly existing and in good
standing (or similar concept


                                      -43-

<PAGE>   49


under applicable law, including, without limitation, the concept of active
status under the laws of the State of Wisconsin) under the laws of the
jurisdiction of its organization, (b) has the limited liability company or
corporate power and authority and the legal right to own and operate all its
material property, to lease the material property it operates as lessee and to
conduct the business in which it is currently engaged, (c) is duly qualified as
a foreign limited liability company or corporation and in good standing under
the laws of each jurisdiction where its ownership, lease or operation of
property or the conduct of its business requires such qualification except to
the extent that the failure to so qualify or be in good standing would not, in
the aggregate, have a Material Adverse Effect and (d) is in compliance with all
Requirements of Law except to the extent that the failure to comply therewith
would not, in the aggregate, reasonably be expected to have a Material Adverse
Effect.

         7.4      Corporate Power; Authorization; Enforceable Obligations. Each
of the Borrower and the other Credit Parties has full power and authority and
the legal right to make, deliver and perform the Credit Documents to which it is
party and has taken all necessary limited liability company or corporate action
to authorize the execution, delivery and performance by it of the Credit
Documents to which it is party. No consent or authorization of, filing with,
notice to or other act by or in respect of, any Governmental Authority or any
other Person is required in connection with the borrowings hereunder or with the
execution, delivery or performance of any Credit Document by the Borrower or the
other Credit Parties (other than those which have been obtained or in connection
with the perfection of Liens in favor of the Agent and Lenders hereunder) or
with the validity or enforceability of any Credit Document against the Borrower
or the Guarantors (except such filings as are necessary in connection with the
perfection of the Liens created by such Credit Documents). Each Credit Document
to which it is a party has been duly executed and delivered on behalf of the
Borrower or the other Credit Parties, as the case may be. Each Credit Document
to which it is a party constitutes a legal, valid and binding obligation of the
Borrower or the Guarantors, as the case may be, enforceable against the Borrower
or the other Credit Parties, as the case may be, in accordance with its terms.

         7.5      No Legal Bar; No Default. The execution, delivery and
performance of the Credit Documents, the borrowings thereunder and the use of
the proceeds of Extensions of Credit will not violate any Requirement of Law the
violation of which would reasonably be expected to have a Material Adverse
Effect or any Contractual Obligation of the Borrower or its Subsidiaries the
violation of which would reasonably be expected to have a Material Adverse
Effect (except those as to which waivers or consents have been obtained), and
will not result in, or require, the creation or imposition of any Lien on any of
its or their respective properties or revenues pursuant to any Requirement of
Law or Contractual Obligation other than the Liens arising under or contemplated
in connection with the Credit Documents. Neither the Borrower nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect which would reasonably be expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

         7.6      No Material Litigation. Except as set forth on Schedule 7.6,
no litigation, investigation or proceeding of or before any arbitrator or
Governmental Authority is pending or, to the best knowledge of the Borrower and
the other Credit Parties, threatened by or against the Borrower or any of its
Subsidiaries or against any of its or their respective properties or revenues
(a) with respect to the Credit Documents or any Loan or any of the transactions
contemplated


                                      -44-

<PAGE>   50


hereby, or (b) which, if adversely determined, would reasonably be expected to
(i) cause an adverse financial effect on the Borrower or any of its Subsidiaries
in excess of $250,000 or (ii) have a Material Adverse Effect.

         7.7      Investment Company Act. Neither the Borrower nor any of the
other Credit Parties is an "investment company", or a company "controlled" by an
"investment company," within the meaning of the Investment Company Act of 1940,
as amended.

         7.8      Federal Regulations. No part of the proceeds of any Loan
hereunder will be used directly or indirectly for any purpose which violates, or
which would be inconsistent with, the provisions of Regulation T, U or X of the
Board of Governors of the Federal Reserve System as now and from time to time
hereafter in effect. The Borrower and its Subsidiaries taken as a group do not
own "margin stock" except margin stock which is a Permitted Investment, but only
to the extent otherwise permitted by this Agreement.

         7.9      ERISA. Neither a Reportable Event nor an "accumulated funding
deficiency" within the meaning of Section 412 of the Code (or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code, except to the extent that any such occurrence or failure to comply
would not reasonably be expected to have a Material Adverse Effect. No
termination of a Single Employer Plan has occurred resulting in any liability
that has remained underfunded, and no Lien in favor of the PBGC or a Plan has
arisen, during such five-year period which would reasonably be expected to have
a Material Adverse Effect. The present value of all accrued benefits under each
Single Employer Plan (based on those assumptions used to fund such Plans) did
not, as of the last annual valuation date prior to the date on which this
representation is made or deemed made, exceed the value of the assets of such
Plan allocable to such accrued benefits by an amount which, as determined in
accordance with GAAP, would reasonably be expected to have a Material Adverse
Effect. Neither the Borrower nor any Commonly Controlled Entity is currently
subject to any liability for a complete or partial withdrawal from a
Multiemployer Plan which would reasonably be expected to have a Material Adverse
Effect. For purposes of this Section 7.9 only, the parties hereto agree that
"Material Adverse Effect" shall include any event referred to in this Section
7.9 which would or could be reasonably expected to cause a reduction in
Consolidated Net Worth of five percent (5%) or more.

         7.10     Environmental Matters. Except as set forth on Schedule 7.10
and except to the extent that all of the following, in the aggregate, would not
reasonably be expected to have a Material Adverse Effect:

                  (a)      To the best knowledge of the Borrower and the other
         Credit Parties, the facilities and properties owned, leased or operated
         by the Borrower or any of its Subsidiaries (the "Properties") do not
         contain any Materials of Environmental Concern in amounts or
         concentrations which (i) constitute a violation of, or (ii) could give
         rise to liability under, any Environmental Law.

                  (b)      To the best knowledge of the Borrower and the other
         Credit Parties, the Properties and all operations at the Properties are
         in compliance, and have in the last five


                                      -45-

<PAGE>   51


         years been in compliance, in all material respects with all applicable
         Environmental Laws, and there is no contamination at, under or about
         the Properties or violation of any Environmental Law with respect to
         the Properties or the business operated by the Borrower or any of its
         Subsidiaries (the "Business").

                  (c)      Neither the Borrower nor any of its Subsidiaries has
         received any notice of violation, alleged violation, non-compliance,
         liability or potential liability regarding environmental matters or
         compliance with Environmental Laws with regard to any of the Properties
         or the Business, nor do the Borrower nor the other Credit Parties have
         knowledge or reason to believe that any such notice will be received or
         is being threatened.

                  (d)      To the best knowledge of the Borrower and the other
         Credit Parties, Materials of Environmental Concern have not been
         transported or disposed of from the Properties in violation of, or in a
         manner or to a location which could give rise to liability under any
         Environmental Law, nor have any Materials of Environmental Concern been
         generated, treated, stored or disposed of at, on or under any of the
         Properties in violation of, or in a manner that could give rise to
         liability under, any applicable Environmental Law.

                  (e)      No judicial proceeding or governmental or
         administrative action is pending or, to the knowledge of the Borrower
         and the other Credit Parties, threatened, under any Environmental Law
         to which the Borrower or any Subsidiary is or will be named as a party
         with respect to the Properties or the Business, nor are there any
         consent decrees or other decrees, consent orders, administrative orders
         or other orders, or other administrative or judicial requirements
         outstanding under any Environmental Law with respect to the Properties
         or the Business.

                  (f)      To the best knowledge of the Borrower and the other
         Credit Parties, there has been no unremediated release or threat of
         release of Materials of Environmental Concern at or from the
         Properties, or arising from or related to the operations of the
         Borrower or any Subsidiary in connection with the Properties or
         otherwise in connection with the Business, in violation of or in
         amounts or in a manner that could give rise to liability under
         Environmental Laws.

         7.11     Use of Proceeds. Extensions of Credit hereunder may be used to
(i) refinance Indebtedness existing under the Original Credit Agreement, (ii)
finance a $7,000,000 loan to C2 pursuant to the terms of the C2 Loan Documents
and (iii) provide for the working capital and other general corporate purposes
of Borrower. In addition, within ninety (90) Business Days of the initial
Extension of Credit, the Borrower will enter into one or more Rate Management
Transactions with one or more financial institutions acceptable to the Required
Lenders in their reasonable discretion, providing for a fixed rate of interest
on a notional amount of at least $20,000,000 in respect of the Term Loan and an
average weighted maturity of at least two (2) years.

         7.12     Subsidiaries. Set forth on Schedule 7.12 is a complete and
accurate list of all Subsidiaries of the Borrower. The outstanding capital stock
and other equity interests of all such

Subsidiaries is validly issued, fully paid and nonassessable (subject to
Wisconsin Statutes Section 180.0622(2)(b)) and is owned, free and clear of all
Liens (other than those arising under or contemplated in connection with the
Credit Documents). Other than ProSource Dedicated Solutions, Inc., none of the
Subsidiaries owns any assets or conducts any business operations. To the extent
otherwise permitted by this Agreement, the Borrower may, from time to time,
amend Schedule 7.12 by delivering (effective upon receipt) to the Agent and each
Lender a copy of such amended Schedule 7.12 which shall (i) be dated the date of
delivery, (ii) be certified by a duly authorized officer of the Borrower as
true, complete and correct as of such date as delivered in replacement for the
Schedule 7.12 previously in effect, and (iii) show in reasonable detail (by
blacklining or other appropriate graphic means) the changes from the predecessor
Schedule 7.12.

         7.13     Taxes. To the best knowledge of the Borrower and the other
Credit Parties, each of the Borrower and its Subsidiaries has filed, or caused
to be filed, all material tax returns (federal, state, local and foreign)
required to be filed and paid all taxes shown thereon to be due (including
interest and penalties) and has paid all other taxes, fees, assessments and
other governmental charges (including mortgage recording taxes, documentary
stamp taxes and intangibles taxes) owing or necessary to preserve any Liens in
favor of the Lenders by them, except for such taxes (i) which are not yet
delinquent or (ii) as are being contested in good faith and by proper
proceedings, and against which adequate reserves are being maintained in
accordance with GAAP. The Borrower is not aware of any proposed material tax
assessments against it or any of its Subsidiaries. The most recent completed
audit of the Borrower's federal income tax returns was for the Borrower's income
tax year ending June 30, 1990, and all taxes shown by such returns (together
with any adjustments arising out of such audit, if any) have been paid.

or omit to state a material fact necessary to make such information not
misleading.

other amounts owing to the Agent or any Lender hereunder, are paid in full, the
Borrower shall, and in the case of subsections 8.3, 8.4, 8.5, 8.6, 8.7, 8.8 and

         immediately preceding clause) other than the Core Interest Owners which
         is unacceptable to the Required Lenders obtains control of more than
         35% of the issued and outstanding voting stock of C2 at a time when the
         Core Interest Owners control less than 51% of the issued and
         outstanding voting stock of C2; or

         force and effect or to give the Agent and/or the Lenders the security
         interests, liens, rights, powers and privileges reasonably purported to
         be created thereby;

then, and in any such event, (A) if such event is an Event of Default specified
in paragraph (e) above, automatically the Commitments shall immediately
terminate and the Loans (with accrued interest thereon), and all other amounts
under the Credit Documents (including, without limitation, the maximum amount of
all contingent liabilities under Letters of Credit which amount shall be paid to
the Agent and held as cash collateral therefor) shall immediately become due and
payable, and (B) if such event is any other Event of Default, either or both of
the following actions may be taken: (i) with the written consent of the Required
Lenders, the Agent may, or upon the written request of the Required Lenders, the
Agent shall, by notice to the Borrower declare the Commitments to be terminated
forthwith, whereupon the Commitments shall immediately terminate; and (ii) with
the written consent of the Required Lenders the Agent may, or upon the written
request of the Required Lenders, the Agent shall, by notice of default to the
Borrower, declare the Loans (with accrued interest thereon) and all other
amounts owing under this Agreement and the Credit Documents to be due and
payable forthwith and direct the Borrower to pay to the Agent cash collateral as
security for the LOC Obligations for subsequent drawings under then outstanding

presentment, demand, protest and all other notices of any kind are hereby
expressly waived.

                                   ARTICLE 11

                                AGENCY PROVISIONS

         11.1     Appointment. Each Lender hereby designates and appoints
Firstar as Agent hereunder of such Lender to act as specified herein and in the
other Credit Documents, and each such Lender hereby authorizes the Agent as the
agent for such Lender, to take such action on its behalf under the provisions of
this Credit Agreement and the other Credit Documents and to exercise such powers
and perform such duties as are expressly delegated by the terms hereof and of
the other Credit Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere
herein and in the other Credit Documents, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein and therein, or any
fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Credit Agreement or any of the other Credit Documents, or shall otherwise exist
against the Agent. The provisions of this Section are solely for the benefit of
the Agent and the Lenders and none of the Credit Parties shall have any rights
as a third party beneficiary of the provisions hereof. In performing its
functions and duties under this Credit Agreement and the other Credit Documents,
the Agent shall act solely as agent of the Lenders and does not assume and shall
not be deemed to have assumed any obligation or relationship of agency or trust
with or for the Borrower or any other Credit Party.

         11.2     Delegation of Duties. The Agent may execute any of its duties
hereunder or under the other Credit Documents by or through agents or
attorneys-in-fact and shall be entitled


                                      -59-

<PAGE>   65


to advice of counsel concerning all matters pertaining to such duties. The Agent
shall not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

         11.3     Exculpatory Provisions. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(i) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection herewith or in connection with any of the other
Credit Documents except for its or such Person's own gross negligence or willful
misconduct, or (ii) responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by any of the Credit
Parties contained herein or in any of the other Credit Documents or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection herewith or in connection with
the other Credit Documents, or enforceability or sufficiency herefor of any of
the other Credit Documents, or for any failure of the Borrower to perform its
obligations hereunder or thereunder. The Agent shall not be responsible to any
Lender for the effectiveness, genuineness, validity, enforceability,
collectability or sufficiency of this Credit Agreement, or any of the other
Credit Documents or for any representations, warranties, recitals or statements
made herein or therein or made by the Borrower or any Credit Party in any
written or oral statement or in any financial or other statements, instruments,
reports, certificates or any other documents in connection herewith or therewith
furnished or made by the Agent to the Lenders or by or on behalf of the Credit
Parties to the Agent or any Lender or be required to ascertain or inquire as to
the performance or observance of any of the terms, conditions, provisions,
covenants or agreements contained herein or therein or as to the use of the
proceeds of the Loans or of the existence or possible existence of any Default
or Event of Default or to inspect the properties, books or records of the Credit
Parties.

         11.4     Reliance on Communications. The Agent shall be entitled to
rely, and shall be fully protected in relying, upon any note, writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document or conversation believed by it to be genuine and correct and to have
been signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel (including, without limitation, counsel to the Agent
and any of the Lenders, independent accountants and other experts selected by
the Agent with reasonable care). The Agent may deem and treat the Lenders as the
owner of their respective interests hereunder for all purposes unless a written
notice of assignment, negotiation or transfer thereof shall have been filed with
the Agent in accordance with Section 12.6(d). The Agent shall be fully justified
in failing or refusing to take any action under this Credit Agreement or under
any of the other Credit Documents unless it shall first receive such advice or
concurrence of the Required Lenders, or all Lenders, as the case may be, as it
deems appropriate. The Agent shall in all cases be fully protected in acting, or
in refraining from acting, hereunder or under any of the other Credit Documents
in accordance with a request of the Required Lenders (or to the extent
specifically provided in Section 12.1, all the Lenders) and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders (including their successors and assigns).

         11.5     Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder (other than the failure by the Borrower to pay any principal or
interest on any Note when due in accordance with the terms


                                      -60-
<PAGE>   66


thereof or hereof) unless the Agent has received notice from a Lender or a
Credit Party referring to the Credit Document, stating that a Default or Event
of Default exists, and specifying the particulars thereof. In the event that the
Agent receives such a notice or the Borrower fails to pay any principal or
interest on any Note when due, the Agent shall give prompt notice thereof to the
Lenders. The Agent shall take such action with respect to such Default or Event
of Default as shall be directed by the Required Lenders, otherwise than an
action that the Agent reasonably believes would be a violation of law or
otherwise prohibited by the Credit Documents.

         11.6     Non-Reliance on Agent and Other Lenders. Each Lender expressly
acknowledges that neither the Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates has made any representations
or warranties to it and that no act by the Agent or any affiliate thereof
hereinafter taken, including any review of the affairs of the Borrower, shall be
deemed to constitute any representation or warranty by the Agent to any Lender.
Each Lender represents to the Agent that it has, independently and without
reliance upon the Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, assets, operations, property, financial and
other conditions, prospects and creditworthiness of the Borrower and made its
own decision to make its Loans hereunder and enter into this Credit Agreement.
Each Lender also represents that it will, independently and without reliance
upon the Agent or any other Lender, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Credit Agreement, and to make such investigation as it deems necessary to inform
itself as to the business, assets, operations, property, financial and other
conditions, prospects and creditworthiness of the Borrower. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Agent hereunder, the Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the business,
operations, assets, property, financial or other conditions, prospects or
creditworthiness of the Borrower which may come into the possession of the Agent
or any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates.

         11.7     Indemnification. The Lenders agree to indemnify the Agent in
its capacity as such (to the extent not reimbursed by the Borrower and without
limiting the obligation of the Borrower to do so), ratably according to their
respective Commitment Percentages (or if the Commitments have expired or been
terminated, in accordance with the respective principal amounts of outstanding
Loans and Participation Interests of the Lenders), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the termination of this
Credit Agreement) be imposed on, incurred by or asserted against the Agent in
its capacity as such in any way relating to or arising out of this Credit
Agreement or the other Credit Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by the Agent under or in connection with any of
the foregoing; provided that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the gross
negligence or willful misconduct of the Agent. If any indemnity furnished to the
Agent for any purpose shall, in the reasonable opinion of the Agent, be
insufficient or become impaired,


                                      -61-

<PAGE>   67


the Agent may call for additional indemnity and cease, or not commence, to do
the acts indemnified against until such additional indemnity is furnished.

         11.8     Agent in its Individual Capacity. The Agent and its affiliates
may make loans to, accept deposits from and generally engage in any kind of
business with the Borrower or any other Credit Party as though the Agent were
not Agent hereunder. With respect to its Loans and Participation Interests, the
Agent shall have the same rights, obligations and powers under this Credit
Agreement as any Lender and may exercise the same as though they were not Agent,
and the terms "Lender" and "Lenders" shall include the Agent in its individual
capacity.

         11.9     Successor Agent. The Agent may, at any time, resign upon 20
days' written notice to the Lenders and the Borrower. Upon any such resignation,
the Required Lenders shall have the right to appoint a successor Agent (which
shall be a Lender) with the prior written consent of the Borrower, which consent
shall not be unreasonably withheld. If no successor Agent shall have been so
appointed by the Required Lenders, and shall have accepted such appointment,
within 30 days after the notice of resignation, as appropriate, then the
retiring Agent shall select a successor Agent provided such successor is a
Lender hereunder or a commercial bank organized under the laws of the United
States of America or of any State thereof and has a combined capital and surplus
of at least $500,000,000. Upon the acceptance of any appointment as Agent
hereunder by a successor, such successor Agent shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the retiring
Agent, and the retiring Agent shall be discharged from its duties and
obligations as Agent, as appropriate, under this Credit Agreement and the other
Credit Documents and the provisions of this Section 11.9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Credit Agreement.

                                   ARTICLE 12

                                  MISCELLANEOUS

         12.1     Amendments, Waivers and Release of Collateral. Neither this
Credit Agreement, nor any of the Notes, nor any of the other Credit Documents,
nor any terms hereof or thereof may be amended, supplemented, waived or modified
except in accordance with the provisions of this subsection nor may collateral
be released except as specifically provided herein or in the Security Agreement
or in accordance with the provisions of this subsection. The Required Lenders
may, or, with the written consent of the Required Lenders, the Agent may, from
time to time, (a) enter into with the Borrower written amendments, supplements
or modifications hereto and to the other Credit Documents for the purpose of
adding, amending or deleting any provisions of this Credit Agreement or the
other Credit Documents or (b) waive, on such terms and conditions as the
Required Lenders may specify in such instrument, any of the requirements of this
Credit Agreement or the other Credit Documents or any Default or Event of
Default and its consequences or (c) release collateral in accordance with the
terms hereof or of the Security Agreement or on such other terms and conditions
as the Required Lenders may agree; provided, however, that no such waiver and no
such amendment, waiver, supplement, modification or release shall (i) reduce the
amount or extend the scheduled date of maturity of any Loan or Note or any
installment thereon, or reduce the stated rate of any interest or fee payable
hereunder (other than interest at the increased post-default rate) or extend the
scheduled date of any

                                      -62-

Lender's Commitment, in each case without the written consent of each Lender
directly affected thereby, or (ii) amend, modify or waive any provision of this
Section 12.1 or reduce the percentage specified in the definition of Required
Lenders, or consent to the assignment or transfer by the Borrower of any of its
rights and obligations under this Credit Agreement, in each case without the
written consent of all the Lenders, or (iii) amend, modify or waive any
provision of Section 11 without the written consent of the then Agent, (iv)
release any of the Guarantors or any of the Collateral having a fair market
value in excess of $1,000,000 (whether individually or collectively with any
other Collateral to be released in connection therewith) without the written
consent of all of the Lenders, or (v) amend Section 4.12 without the written
consent of all Lenders. Any such waiver, any such amendment, supplement or
modification and any such release shall apply equally to each of the Lenders and
shall be binding upon the Borrower, the Lenders, the Agent and all future
holders of the Notes. In the case of any waiver, the Borrower, the Lenders and
the Agent shall be restored to their former position and rights hereunder and
under the outstanding Loans and Notes and other Credit Documents, and any
Default or Event of Default waived shall be deemed to be cured and not
continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default, or impair any right consequent thereon.

         12.2     Notices. Except as otherwise provided in Section 3, all
notices, requests and demands to or upon the respective parties hereto to be

         12.3     No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising, on the part of the Agent or any Lender, any right, remedy,
power or privilege hereunder shall operate as a waiver thereof; nor shall any

preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege. The rights, remedies, powers and privileges
herein provided are cumulative and not exclusive of any rights, remedies, powers
and privileges provided by law.

         12.4     Survival of Representations and Warranties. All
representations and warranties made hereunder and in any document, certificate
or statement delivered pursuant hereto or in connection herewith shall survive

amounts owing hereunder and under any Notes have been paid in full.

         12.5     Payment of Expenses and Taxes. The Borrower agrees (a) to pay
or reimburse the Agent for all its reasonable out-of-pocket costs and expenses
incurred in connection with the preparation and execution of, and any amendment,

prepared in connection herewith or therewith, and the consummation of the
transactions contemplated hereby and thereby, together with the reasonable fees
and disbursements of counsel to the Agent, (b) to pay out-of-pocket expenses,
including attorneys' fees, incurred by a Lender in connection with the
negotiation, preparation and execution of the Credit Documents, not to exceed
$2,500 for each Lender, and reasonable expenses, including reasonable attorneys'
fees, in connection with any future amendments or

                                      -64-

<PAGE>   70


modifications hereto, (c) to pay or reimburse each Lender and the Agent for all
its costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Credit Agreement and any other Credit
Documents, including, without limitation, the reasonable fees and disbursements
of counsel to the Agent and to the Lenders (including reasonable allocated costs
of in-house legal counsel), (d) on demand, to pay, indemnify, and hold each
Lender and the Agent harmless from, any and all recording and filing fees and
any and all liabilities with respect to, or resulting from any delay in paying,
stamp, excise and other similar taxes, if any, which may be payable or
determined to be payable in connection with the execution and delivery of, or
consummation or administration of any of the transactions contemplated by, or
any amendment, supplement or modification of, or any waiver or consent under or
in respect of, the Credit Documents and any such other documents, and (e) to
pay, indemnify, and hold each Lender and the Agent and their Affiliates,
officers, directors, shareholders, employees and agents harmless from and
against, any and all other liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of the Credit Documents and any such other
documents and the use, or proposed use, of proceeds of the Loans (all the
foregoing, collectively, the "Indemnified Liabilities"); provided, however, that
the Borrower shall not have any obligation hereunder to the Agent or any Lender
with respect to Indemnified Liabilities arising from (i) the gross negligence or
willful misconduct of the Agent or any such Lender, (ii) legal proceedings
commenced against or disputes among the Agent or any Lender by any other Lender
or its participants or the Agent, or (iii) the violation by the Agent or any
such Lender of an express provision of the Credit Documents, if so determined by
a final judgment of a court of competent jurisdiction. The agreements in this
Section 12.5 shall survive repayment of the Loans, Notes and all other amounts
payable hereunder.

         12.6     Successors and Assigns; Participations; Purchasing Lenders.

                  (a)      This Credit Agreement shall be binding upon and inure
         to the benefit of the Borrower, the Lenders, the Agent, all future
         holders of the Notes and their respective successors and assigns,
         except that the Borrower may not assign or transfer any of its rights
         or obligations under this Credit Agreement or the other Credit
         Documents without the prior written consent of each Lender and no
         Lender may assign or transfer any of its rights or obligations under
         this Credit Agreement or the other Credit Documents without the prior
         written consent of the Borrower, except as otherwise permitted by this
         Section 12.6.

                  (b)      Any Lender may, in the ordinary course of its
         commercial banking business and in accordance with applicable law and,
         so long as no Event of Default has occurred and is continuing, with the
         consent of the Borrower (which consent shall not be unreasonably
         withheld), at any time sell to one or more banks or other entities
         ("Participant" or "Participants") participating interests in any Loan
         owing to such Lender, any Note held by such Lender, any Commitment of
         such Lender, or any other interest of such Lender hereunder, provided,
         however, that at all times such Lender shall retain for its own account
         interests in Loans owing to such Lender in an aggregate outstanding
         principal amount which, when added to the aggregate outstanding
         principal amount of any interests in Loans sold by such Lender to
         Participants who are Affiliates of such


                                      -65-

<PAGE>   71


         Lender, equals not less than fifty percent (50%) of the aggregate
         principal amount of all such Lender's outstanding Loans. In the event
         of any such sale by a Lender of participating interests to a
         Participant, such Lender's obligations under this Credit Agreement to
         the other parties to this Credit Agreement shall remain unchanged, such
         Lender shall remain solely responsible for the performance thereof,
         such Lender shall remain the holder of any such Note for all purposes
         under this Credit Agreement, and the Borrower and the Agent shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under this Credit Agreement.
         No Lender shall transfer or grant any participation under which the
         Participant shall have rights to approve any amendment to or waiver of
         this Credit Agreement or any other Credit Document except to the extent
         such amendment or waiver would (i) extend the scheduled maturity of any
         Loan or Note or any installment thereon in which such Participant is
         participating, or reduce the stated rate or extend the time of payment
         of interest or Fees thereon except in connection with a waiver of
         interest at the increased post-default rate) or reduce the principal
         amount thereof, or increase the amount of the Participant's
         participation over the amount thereof then in effect it being
         understood that a waiver of any Default or Event of Default shall not
         constitute a change in the terms of such participation, and that an
         increase in any Commitment or Loan shall be permitted without consent
         of any Participant if the Participant's participation is not increased
         as a result thereof, (ii) release all or substantially all of the
         collateral, or (iii) consent to the assignment or transfer by the
         Borrower of any of its rights and obligations under this Credit
         Agreement. In the case of any such participation, the Participant shall
         not have any rights under this Credit Agreement or any of the other
         Credit Documents (the Participant's rights against such Lender in
         respect of such participation to be those set forth in the agreement
         executed by such Lender in favor of the Participant relating thereto)
         and all amounts payable by the Borrower hereunder shall be determined
         as if such Lender had not sold such participation, provided that each
         Participant shall be entitled to the benefits of Sections 4.6, 4.7,
         4.8, 4.9 and 12.5 with respect to its participation in the Commitments
         and the Loans outstanding from time to time; provided, that no
         Participant shall be entitled to receive any greater amount pursuant to
         such Sections than the transferor Lender would have been entitled to
         receive in respect of the amount of the participation transferred by
         such transferor Lender to such Participant had no such transfer
         occurred.

                  (c)      Any Lender may, in the ordinary course of its
         commercial banking business and in accordance with applicable law, at
         any time sell or assign (i) to any Lender or any Affiliate thereof,
         except that any such sale or assignment shall be made only with the
         consent of the Borrower if such sale or assignment would increase any
         amount payable by the Borrower hereunder, or (ii) to one or more
         additional banks or financial institutions ("Purchasing Lenders"),
         except that any such sale or assignment shall be made only with the
         consent of the Agent and, so long as no Event of Default has occurred
         and is continuing or at any time if any such sale or assignment would
         increase any amount payable by the Borrower hereunder, the consent of
         the Borrower: all or any part of its rights and obligations under this
         Credit Agreement and the Notes in minimum amounts of $10,000,000 (or,
         if less, the entire amount of such Lender's obligations) if the
         Purchasing Lender is not a Lender hereunder, or with no minimum amount
         if the Purchasing Lender is a Lender hereunder, pursuant to a
         Commitment Transfer


                                      -66-

<PAGE>   72


         Supplement, executed by such Purchasing Lender, such transferor Lender
         (and, in the case of a Purchasing Lender that is not then a Lender or
         an affiliate thereof so long as no Event of Default has occurred and is
         continuing, by the Borrower and the Agent), and delivered to the Agent
         for its acceptance and recording in the Register. Upon such execution,
         delivery, acceptance and recording, from and after the Transfer
         Effective Date specified in such Commitment Transfer Supplement, (x)
         the Purchasing Lender thereunder shall be a party hereto and, to the
         extent provided in such Commitment Transfer Supplement, have the rights
         and obligations of a Lender hereunder with a Commitment as set forth
         therein, and (y) the transferor Lender thereunder shall, to the extent
         provided in such Commitment Transfer Supplement, be released from its
         obligations under this Credit Agreement (and, in the case of a
         Commitment Transfer Supplement covering all or the remaining portion of
         a transferor Lender's rights and obligations under this Credit
         Agreement, such transferor Lender shall cease to be a party hereto).
         Such Commitment Transfer Supplement shall be deemed to amend this
         Credit Agreement to the extent, and only to the extent, necessary to
         reflect the addition of such Purchasing Lender and the resulting
         adjustment of Commitment Percentages arising from the purchase by such
         Purchasing Lender of all or a portion of the rights and obligations of
         such transferor Lender under this Credit Agreement and the Notes. On or
         prior to the Transfer Effective Date specified in such Commitment
         Transfer Supplement, the Borrower, at its own expense, shall execute
         and deliver to the Agent in exchange for the Note delivered to the
         Agent pursuant to such Commitment Transfer Supplement a new Note to the
         order of such Purchasing Lender in an amount equal to the Commitment
         assumed by it pursuant to such Commitment Transfer Supplement and,
         unless the transferor Lender has not retained a Commitment hereunder, a
         new Note to the order of the transferor Lender in an amount equal to
         the Commitment retained by it hereunder. Except for the expense of
         executing and delivering such new Note to the Agent pursuant to this
         Section, the Borrower shall not be obligated to pay any transfer fees,
         costs or expenses to the Agent or any Lender in connection with any
         such transfer. Such new Note shall be dated the Closing Date and shall
         otherwise be in the form of the Note replaced thereby. The Note
         surrendered by the transferor Lender shall be returned by the Agent to
         the Borrower marked "canceled."

                  (d)      The Agent shall maintain at its address referred to
         in Section 12.2 a copy of each Commitment Transfer supplement delivered
         to it and a register (the "Register") for the recordation of the names
         and addresses of the Lenders and the Commitment of, and principal
         amount of the Loans owing to, each Lender from time to time. The
         entries in the Register shall be conclusive, in the absence of manifest
         error, and the Borrower, the Agent and the Lenders may treat each
         Person whose name is recorded in the Register as the owner of the Loan
         recorded therein for all purposes of this Credit Agreement. The
         Register shall be available for inspection by the Borrower or any
         Lender at any reasonable time and from time to time upon reasonable
         prior notice.

                  (e)      Upon its receipt of a Commitment Transfer Supplement
         executed by a transferor Lender and a Purchasing Lender and, in the
         case of a Purchasing Lender that is not then a Lender (or an affiliate
         thereof, by the Borrower and the Agent) together with payment to the
         Agent by the transferor Lender or the Purchasing Lender, (as agreed
         between them) of a registration and processing fee of $2,500 for each
         Purchasing Lender


                                      -67-

<PAGE>   73


         listed in such Commitment Transfer Supplement, and the Notes subject to
         such Commitment Transfer Supplement, the Agent shall (i) accept such
         Commitment Transfer Supplement, (ii) record the information contained
         therein in the Register and (iii) give prompt notice of such acceptance
         and recordation to the Lenders and the Borrower.

                  (f)      The Borrower authorizes each Lender to disclose to
         any Participant or Purchasing Lender each, (a "Transferee") and any
         permitted prospective Transferee any and all financial information in
         such Lender's possession concerning the Borrower and its Affiliates
         which has been delivered to such Lender by or on behalf of the Borrower
         pursuant to this Credit Agreement or which has been delivered to such
         Lender by or on behalf of the Borrower in connection with such Lender's
         credit evaluation of the Borrower and its Affiliates prior to becoming
         a party to this Credit Agreement.

                  (g)      At the time of each assignment pursuant to this
         Section 12.6 to a Person which is not already a Lender hereunder and
         which is not a United States person (as such term is defined in Section
         7701(a)(30) of the Code) for Federal income tax purposes, the
         respective assignee Lender shall provide to the Borrower and the Agent
         the appropriate Internal Revenue Service Forms (and, if applicable, a
         U.S. Tax Compliance Certificate) described in Section 4.9.

                  (h)      Nothing herein shall prohibit any Lender from
         pledging or assigning any of its rights under this Credit Agreement
         (including, without limitation, any right to payment of principal and
         interest under any Note) to any Federal Reserve Bank in accordance with
         applicable laws.

         12.7     Set-off. In addition to any rights and remedies of the Lenders
provided by law (including, without limitation, other rights of set-off), each
Lender shall have the right, without prior notice to the Borrower, any such
notice being expressly waived by the Borrower to the extent permitted by
applicable law, upon the occurrence and during the continuance of any Event of
Default, to setoff and appropriate and apply any and all deposits (general or
special, time or demand, provisional or final), in any currency, and any other
credits, indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender or any Affiliate, branch or agency thereof to or for the
credit or the account of the Borrower, or any part thereof in such amounts as
such Lender may elect, against and on account of the obligations and liabilities
of the Borrower to such Lender hereunder and claims of every nature and
description of such Lender against the Borrower, in any currency, whether
arising hereunder, under the Notes or under any documents contemplated by or
referred to herein or therein, as such Lender may elect, whether or not such
Lender has made any demand for payment. The aforesaid right of set-off may be
exercised by such Lender against the Borrower or against any trustee in
bankruptcy, debtor in possession, assignee for the benefit of creditors,
receiver or execution, judgment or attachment creditor of the Borrower, or
against anyone else claiming through or against the Borrower or any such trustee
in bankruptcy, debtor in possession, assignee for the benefit of creditors,
receiver, or execution, judgment or attachment creditor, notwithstanding the
fact that such right of set-off shall not have been exercised by such Lender
prior to the occurrence of any Event of Default. Each Lender agrees promptly to
notify the Borrower and the Agent after any such set-off and application


                                      -68-

<PAGE>   74


made by such Lender; provided, however, that the failure to give such notice
shall not affect the validity of such set-off and application.

         12.8     Confidentiality. The Agent and each Lender shall hold in
confidence any material nonpublic information delivered or made available to
them by the Borrower. Notwithstanding the foregoing, nothing herein shall
prevent the Agent or any Lender from disclosing any information delivered or
made available to it by the Borrower (a) to such Lender's Affiliates, the Agent
or any Lender, (b) upon the order of any court or administrative agency, (c)
upon the request or demand of any regulatory agency or authority, (d) which has
been publicly disclosed other than as a result of a disclosure by the Agent or
any Lender which is not permitted by this Agreement, (e) to the extent
reasonably required in connection with any litigation to which the Agent, any
Lender, or any of their respective affiliates may be a party, along with the
Borrower, any Subsidiary or any of their respective Affiliates, (f) to the
extent reasonably required in connection with the exercise of any right or
remedy under this Agreement, (g) to such Agent's or Lender's legal counsel and
financial consultants and independent auditors, and (h) to any Transferee or
permitted prospective Transferee and such Transferee or permitted prospective
Transferee agrees in writing to be bound by the duty of confidentiality under
this Section to the same extent as if it were a Lender hereunder.

         12.9     Table of Contents and Section Headings. The table of contents
and the Section and subsection headings herein are intended for convenience only
and shall be ignored in construing this Credit Agreement.

         12.10    Counterparts. This Credit Agreement may be executed by one or
more of the parties to this Credit Agreement on any number of separate
counterparts, and all of said counterparts taken together shall be deemed to
constitute one and the same instrument. A set of the copies of this Credit
Agreement signed by all the parties shall be lodged with the Borrower and the
Agent.

         12.11    Severability. Any provision of this Credit Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         12.12    Integration. This Credit Agreement, the Notes and the other
Credit Documents represent the agreement of the Borrower, the Agent and the
Lenders with respect to the subject matter hereof, and there are no promises,
undertakings, representations or warranties by the Agent, the Borrower or any
Lender relative to the subject matter hereof not expressly set forth or referred
to herein or in the Notes.

         12.13    Governing Law. This Credit Agreement and the Notes and the
